UNF (Unified National Fine) thread is the fine pitch counterpart to UNC. The fine pitch has greater resistance to being loosened by vibration and the smaller lead angle allows for finer tension adjustment. As such, it is often specified in vehicles and aerospace, especially if manufactured in North America. UNF fasteners are sized in imperial units, similar to BSF fasteners, but the two are differentiated by the angle of the thread profile. We supply UNF threaded bar in 3 foot lengths in steel and stainless steel. We also offer UNF hexagon full nuts, hex setscrews, hex bolts and socket cap screws.
